Emerson Telecom Rectifier r48-1800a 48v 1800w

For a higher load capacity, rectifiers can be connected in parallel and intelligent control can be added with the help of a separate controller.

Product Description

Emerson Telecom Rectifier r48-1800a 48v 1800w

Optimized depth reduced footprint
allows installation in short-depth racks
and cabinets
DSP (Digital Signaling Processor)
means fewer components, optimized
operation and active load sharing for
increased reliability
Compliant with global standards
delivers quality, performance
and reliability no matter what the
application or location demands
High efficiency, up to 91% reduces
power consumption for lower
operating costs
Hot pluggable facilitates future
extensions
Wide input voltage range operates in
the most demanding environments
where input voltage changes
Wide temperature operating range
(-40°C / -40°F to +80°C / 176°F) – meets
the harshest climatic environment
requirements
